Gas manufacturer combines machining operations

Nutberry has invested in a DMG MORI machine and is now using a NLX2500 to reduce the number of operations and help produce more complex parts.

The company has had previous experience with DMG MORI machines, and working together, more versatile bar fed machine with driven tools were achieved. Director of Nutberry, Antony Montebello said: “With the advances in gas spring design, we needed to perform both turning and milling operations to manufacture the end fittings. With the NLX 2000 SY | 500 we have eliminated these extra operations. The patented balanced spring design includes two chambers, extra drilling operations and flats on the rams, all ideal for the NLX 2000 SY | 500’s driven tooling.”

The aim of this gas spring is to control the clamping force as on some occasions the clamping force can be too great at high temperature. The second chamber pressurises as the temperature rises providing an opposing force, keeping the overall clamping force within tolerance.

The NLX 2000 SY | 500 comes with CELOS and has a spindle 2, built in motor turret, part catcher, controlled thermal displacement through coolant circulation in the machine body and high vibration damping performance from its rigid construction.

The CELOS system allows a switch between jobs easily. Programming of the driven tools and spindle 2 is simplified and speeded up with verification of the tool path, making it possible for a finished part to be collected by the part catcher.

Antony Montebello added, “The machine has plenty of power to cut the most demanding materials we work with, such as ESR Stainless Steel, The accuracy so far has led to a reduced number of scrap rates, while the reduction in operations frees up the operator for other tasks and gives us the opportunity to run extra shifts through automation.
